AC Won’t Cool? Here’s Why

You rely on your AC to supply a steady stream of cold air to keep your home at a comfortable temperature. During warmer spring and summer months, you’ll most likely be running your air conditioner a lot. When your unit fails to cool your home, you can be left feeling frustrated and overwhelmed. Read on to learn about common reasons why your AC may not be effectively cooling your home.

Clogged Air Filters

Your air filters trap substances like dirt, dust and pollen and prevent them from recirculating through your air ducts. If you’ve neglected to change your air filters regularly, less air will be able to pass through your system. When this happens, your unit has to work extra hard to cool your home. Clogged air filters can also cause the evaporator coils to freeze, which could block any cool air from going into your home. Check for dirty air filters often, and replace them at least once every three months to reduce wear and tear on your AC unit.

Low Refrigerant Levels

The refrigerant in your air conditioning system absorbs excess heat from your home and cools it off. If you notice ice buildup on the refrigerant lines or the outdoor part of your unit, you may be dealing with low refrigerant levels. In this situation, it’s highly important to shut your unit off immediately and consult with a professional. Continuing to run your AC with low refrigerant levels could cause permanent damage to the compressor.

Dead Thermostat Batteries

In some cases, there may not be anything wrong with your air conditioning system. If your thermostat isn’t displaying any information, the culprit may be as simple as dead batteries. Replacing the batteries should be your first line of defense when your thermostat screen appears blank.
